Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Form the body of the dish, becoming soft and sweet when boiled and simmered.
- Milk
- Provides the liquid base that forms a creamy sauce around the onions.
- Butter
- Adds fat for richness and a smooth mouthfeel to the sauce.
- Corn-starch
- Thickens the milk as it heats, giving the sauce body so it clings to the onions.
The step that matters
Adding the corn-starch mixture. Corn-starch must be mixed with milk first and added to hot liquid while stirring; lumps form if it is dropped in dry, and starch only thickens fully once the mixture simmers.
Swap the onion
How well each one fits the dish's main ingredients (milk, butter, corn, parsley, pepper):
- Potatofits better
- Capsicumfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against milk, butter, corn, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
